Definitions

  • the present invention relates to a sewing machine needle used for sewing in a sewing machine.
  • a sewing machine needle provided with a long groove for reducing frictional resistance between a needle thread and a piece of cloth has been put to practical use. Assume that such a sewing machine needle is used. In this case, when the sewing machine needle penetrates fabric serving as an object to be sewn, the needle thread that has already been run through a needle eye is guided along the long groove and drawn to a place under the fabric. The needle thread drawn to the place under the fabric forms a loop when the sewing machine needle moves up. The loop is caught by a hook on a back side of the sewing machine needle to thereby form a stitch.
  • the loop may not be successfully caught by the hook to thereby lead to occurrence of a problem of stitch skipping etc.
  • the loop may collapse to be thereby unable to be successfully caught by the hook.
  • the hook may not go into the loop to thereby fail in catching the needle thread.
  • inventions for setting the width or depth of a long groove in two stages to thereby suppress movement of a needle thread have been disclosed, for example, in JP-Y-60-10542 and JP-B-7-63554.
  • the width of the long groove on a shank side is formed narrowly.
  • movement of the needle thread can be suppressed so that a loop can be formed stably.
  • the needle thread is retained due to friction that is caused when the needle thread is interposed between the long groove and fabric.
  • the width of the long groove is formed to be narrow or shallow. Accordingly, there is a possibility that the friction caused between the needle thread and the long groove or the fabric may increase over a wide range of the needle thread to thereby increase damage to the needle thread. In addition, large friction is also caused when the needle thread goes into the long groove narrow in width. Accordingly, there is a problem that the wide range of the needle thread may be also damaged on this occasion.
  • the shape of the long groove has to be changed entirely. That is, the machining range is widened. Accordingly, there is a problem that a manufacturing process or quality control may be complicated. For example, there is a problem that the machining may be difficult because the narrow and deep groove has to be cut, or there is a problem that accuracy of a connection portion may be required when the groove is machined in two stages.
  • an object of the invention is to provide a sewing machine needle by which a loop can be formed stably and that causes less damage to a needle thread and can be also manufactured easily.
  • the invention has been accomplished in order to solve the aforementioned problems.
  • the invention is characterized as follows.
  • a sewing machine needle including: a shank portion that is attached to a sewing machine; and a shaft portion that is provided on a front end side of the shank portion; wherein: a needle eye is formed to penetrate the shaft portion, and a long groove for guiding a thread from a position of the needle eye toward the shank portion is formed in the shaft portion; and a suppression portion for suppressing movement of the thread is provided in an intermediate portion of the long groove.
  • the suppression portion is formed so that a sectional area of the groove is smaller in the intermediate portion of the long groove, in addition to the aforementioned characteristic of the invention according to the first configuration.
  • the suppression portion is shaped like a dovetail groove in which width between opening edges is reduced in the long groove, in addition to the aforementioned characteristic of the invention according to the first configuration.
  • the entire suppression portion can move to a place under fabric serving as an object to be sewn when the sewing machine needle is attached to the sewing machine in use, in addition to the aforementioned characteristic of the invention according to any one of the first to third configurations.
  • the needle eye is formed to penetrate the shaft portion, and the long groove for guiding the thread from the position of the needle eye toward the shank portion is formed in the shaft portion; and the suppression portion for suppressing movement of the thread is provided in the intermediate portion of the long groove. According to such a configuration, movement of a needle thread is suppressed by the suppression portion. Thus, a loop can be formed stably.
  • the suppression portion is provided locally in the intermediate portion of the long groove. Accordingly, a range in which a load is applied to the needle thread can be narrowed so that damage to the needle thread can be minimized.
  • the range of the suppression portion is narrow. Accordingly, a range in which friction may be caused when the needle thread goes into the suppression portion is also narrow. As a result, the damage to the needle thread can be minimized.
  • the machining range for forming the suppression portion is narrow. Accordingly, the sewing machine needle can be also manufactured easily without the necessity of entirely changing the shape of the long groove.
  • the suppression portion is formed so that the sectional area of the groove is smaller in the intermediate portion of the long groove. According to such a configuration, movement of the thread can be suppressed due to contact resistance between an inner surface of the groove and the needle thread.
  • the suppression portion is shaped like the dovetail groove in which the width between the opening edges is reduced in the long groove. According to such a configuration, the needle thread can be prevented from easily coming off the suppression portion. Thus, the needle thread can be surely retained. In addition, the needle thread retained by the suppression portion can be prevented from easily touching the fabric. Thus, friction between the fabric and the needle thread can be prevented from being easily caused. That is, damage received by the needle thread can be suppressed.
  • the entire suppression portion can move to the place under the fabric serving as the object to be sewn when the sewing machine needle is attached to the sewing machine in use.
  • the needle thread can be retained in the vicinity of the needle eye. Accordingly, formation of a loop on the suppression portion side can be suppressed so that the loop can be formed stably on the back side.
  • the needle thread is pushed into the suppression portion by the fabric. Accordingly, the needle thread can be surely retained by the suppression portion.

  • FIG. 10 is a view for explaining a state when the sewing machine needle according to the background art is attached to a sewing machine in use, specifically a situation that a loop of the needle thread is too small to be caught by the hook.
  • a sewing machine needle 10 according to the embodiment is provided with a shank portion 11 and a shaft portion 12 .
  • the shank portion 11 is attached to a sewing machine.
  • the shaft portion 12 is provided on a front end side of the shank portion 11 .
  • the shaft portion 12 is a part that can penetrate fabric 20 serving as an object to be sewn.

  • the suppression portion 16 serves for suppressing movement of the needle thread 21 .
  • the suppression portion 16 is formed in such a manner that a sectional area of the groove in the suppression portion 16 is smaller than that in the parallel portion 15 . Thus, movement of the thread can be suppressed due to contact resistance between an inner surface of the groove in the suppression portion 16 and the needle thread 21 .
  • the width of the bottom of the groove in the suppression portion 16 is the same as that in the parallel portion 15 but opposite side surfaces 16 a of the suppression portion 16 slant so as to be gradually closer to each other as going toward opening edges 16 b respectively. Therefore, the suppression portion 16 is shaped like a dovetail groove in which the width between the opening edges 16 b is reduced in the long groove 14 .
